Juicing has become an increasingly popular way for health-conscious consumers to get more vitamins, minerals, and nutrients into their diets. With the wide variety of juicers on the market, it can be tricky to determine which type of juicer is right for your needs. In this article, we’ll take an in-depth look at the Green Star juicer and examine whether or not it can be classified as a true cold press juicer.
What is a Cold Press Juicer?
Cold press juicers, also known as masticating or slow juicers, work by first crushing fruits and vegetables and then pressing them to extract the juice. This happens through a cold press process that does not generate heat and oxidize the produce like some centrifugal juicers do. The two main defining features of cold press juicers are:
- Slow speeds – Cold press juicers operate at much slower speeds, usually around 80-100 RPMs compared to centrifugal juicers which spin at up to 15,000 RPMs.
- Cold processing – The slower speeds ensure the ingredients are not exposed to heat which could destroy nutrients and enzymes.
Compared to centrifugal juicers, cold press models typically yield more juice and extract more nutrients, vitamins, minerals and enzymes. The juice also lasts longer when refrigerated due to the minimal oxidation.
Green Star Juicer Overview
The Green Star juicer is a masticating juicer made by Tribest. It uses a twin gear impeller and press system to crush and then “cold press” fruit and vegetable fibers in order to extract the maximum amount of juice. Some key features and specs of the Green Star juicer include:
- Twin stainless steel impeller gears
- Gears turn at 110 RPMs
- Magnetic and bioceramic technology helps extract minerals
- Automatic pulp ejection for continuous juicing
- 12 year warranty
Based on the slow speed of 110 RPMs, the Green Star would qualify as a cold press juicer in that regard. But let’s take a deeper look at how it actually processes ingredients to see if it meets the definition of a true cold press juicer.
How the Green Star Juicer Works
The Green Star juicer uses a twin gear impeller press system to first crush and then press produce in order to make juice. Here are the key steps in how it works:
- Produce drops into the twin gears.
- The stainless steel gears with specialized pockets turn at 110 RPMs to crush and grind the produce into smaller pieces.
- The smaller pieces of produce drop between the gears into the juicing pocket where the two gears mesh.
- In the juicing pocket, the gears press the produce at high pressure to squeeze out the juice.
- The dry pulp is ejected out the front into a container.
- The juice flows out of the press and into a juice pitcher.
This twin gear impeller and press process allows the Green Star juicer to efficiently grind up produce and then squeeze out the juice in a slow, cold process without introducing a lot of heat or oxygen.
Is the Green Star a Cold Press Juicer?
Based on the technical criteria of how it actually processes fruits and vegetables, the Green Star would definitively qualify as a true cold press juicer. Here are some reasons why:
- Runs at slow 110 RPM speed
- Gears crush produce then press at high pressure
- Minimal heat or oxidation introduced
- Higher juice yields than centrifugal juicers
- Juice can be stored for longer without degradation
The method the Green Star uses to first crush and then press ingredients results in juice that has very high nutrient content and enzymes that isn’t degraded by heat and oxidation like juice made in centrifugal juicers. So for those looking specifically for a cold press juicer, the Green Star would be an excellent choice.
Green Star Juicer Pros and Cons
Here is an overview of some of the key pros and cons of the Green Star juicer based on its performance and ease of use:
- Produces high-nutrient juice in a cold process
- Juice has very little foam and separation
- Automatic pulp ejection for continuous juicing
- 12 year warranty covers parts and performance
- Relatively easy to use and assemble
- Pusher required for firm fruits and veggies
- More parts to clean than a centrifugal model
- Higher price than centrifugal juicers
- Not ideal for juicing softer fruits like citrus
Overall, the Green Star gets very high marks for juice quality and performance. The only downsides are the higher price, and it requires a little more prep work and cleaning than simpler centrifugal juicers. But for the best cold pressed juice, it delivers excellent results.
How Green Star Compares to Other Slow Juicers
The Green Star juicer is one of the most popular masticating/cold press juicer models. Here is how it compares to some other top-rated slow juicers in terms of key features and benefits:
|Juicer||RPMs||Feed Chute||Juice Quality||Ease of Use|
|Kuvings CS600||60||Large||Very Good||Easy|
The Green Star holds it own against these other top cold press juicers in terms of juice quality and yield. It does require a little more prep work up front compared to those with larger feed chutes like the Kuvings. But for maximum nutrient extraction, the Green Star is one of the best performing masticating juicers available.
Is the Green Star Juicer Worth the Investment?
With a price tag ranging from $380 to $600 depending on the model, the Green Star juicer is on the higher end for a slow juicer. Is it worth the significant investment compared to more affordable options like the Omega J8006 at around $300?
Here are some factors to consider when determining if the higher price of the Green Star is justified:
- Juicing Frequency – If you juice daily or almost daily, the Green Star is worth it. Infrequent juicers may be better off with a cheaper model.
- Nutrient Quality – The juice from the Green Star tests higher in enzymes, vitamins and minerals than competitors.
- Juice Yield – You can expect 10-20% higher juice yields compared to other slow juicers.
- Durability – With mostly stainless steel parts, the Green Star holds up extremely well over years of frequent use.
- Warranty – The exceptional 12 year warranty provides peace of mind on the investment.
For serious juicing enthusiasts who want maximum nutrition and enzyme quality, the higher price tag of the Green Star juicer can definitely pay off in the long run through better juice and durability. Occasional juicers may not see enough benefit to justify the cost.
When it comes to masticating or cold press juicers, the Green Star stands out as one of the top performers. It checks off all the boxes for the key criteria like a slow RPM, cold production process, andhighest juice yields. Minor drawbacks are relatively small in comparison to the high quality juice you can expect from the Green Star juicer. For anyone looking to make a significant investment in their juicing habits and health, the Green Star is highly recommended as a cold press juicer that delivers excellent results.
